Question Summary:
Is it a good idea to put baskets of miswaaks in different masaajid with a sign on top describing the virtues of using a miswaak?

Question Detail:

 
I would like to know if I can put a basket of miswaks in different masajid with a sign on top describing the virtues of miswak. My intention is to spread the sunnah but I dont want it to be a bidah if it becomes popular and other masajid follow and do the same thing.
So do you think it is a good idea or not?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
The idea of placing miswaaks in a basket with the virtues of miswaak is actually an attempt to promote the Sunnah of miswaak. It is not bid’ah.[1]
It will be, in fact, encouraged for other masaajid to promote the sunnah of miswaak in the same or similar manner.
Hereunder are the virtues of using a miswaak:
"‏ تَسَوَّكُوا فَإِنَّ السِّوَاكَ مَطْهَرَةٌ لِلْفَمِ مَرْضَاةٌ لِلرَّبِّ وَمَا جَاءَنِي جِبْرِيلُ إِلاَّ أَوْصَانِي بِالسِّوَاكِ حَتَّى لَقَدْ خَشِيتُ أَنْ يُفْرَضَ عَلَىَّ وَعَلَى أُمَّتِي وَلَوْلاَ أَنِّي أَخَافُ أَنْ أَشُقَّ عَلَى أُمَّتِي لَفَرَضْتُهُ لَهُمْ وَإِنِّي لأَسْتَاكُ حَتَّى لَقَدْ خَشِيتُ أَنْ أُحْفِيَ مَقَادِمَ فَمِي ‏"
It was narrated from Abu Umamah that: The Messenger of Allah said: "Use the miswaak, for the miswaak purifies the mouth and is pleasing to the Lord. Jibril never came to me but he advised me to use the miswaak, until I feared that it would be made obligatory for me and my Ummah. Were it not that I fear that it would be too difficult for my Ummah, I would have enjoined it upon them. And I use the miswaak until I fear that I may make the front of my mouth sore.' (i.e. my gums) (or cause my teeth to fall out due to brushing them so often)."[2]
عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «قَدْ أَكْثَرْتُ عَلَيْكُمْ فِي السِّوَاكِ»
It was narrated that Anas bin Malik said: "The Messenger of Allah (ﷺ) said: 'I have indeed urged you with regard to the miswaak.'"[3]
8 - أَخْبَرَنَا عَلِيُّ بْنُ خَشْرَمٍ قَالَ: حَدَّثَنَا عِيسَى وَهُوَ ابْنُ يُونُسَ، عَنْ مِسْعَرٍ، عَنِ الْمِقْدَامِ وَهُوَ ابْنُ شُرَيْحٍ، عَنْ أَبِيهِ قَالَ: قُلْتُ لِعَائِشَةَ بِأَيِّ شَيْءٍ كَانَ يَبْدَأُ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ إِذَا دَخَلَ بَيْتَهُ؟ قَالَتْ: «بِالسِّوَاكِ»
It was narrated from Al-Miqdam - Abu Shuraih - that his father said: "I said to 'Aishah: 'What did the Prophet (ﷺ) start with when he entered his house?' She said: 'The miswaak.'"[4]
